Air Traffic Federal Aviation Administration Environmental Program By: Ryan Weller - FAA/ATO Date: April 26, 2018
Air Traffic Environmental • NEPA requires FAA to: – Address impacts of major federal actions on the human environment including noise, socioeconomic, land uses, air quality, water quality and others – Depending upon the context and potential impacts, NEPA analysis can differ – Levels of NEPA • Action not subject to NEPA/No further env. action • CATEX – Categorical Exclusion • EA – Environmental Assessment • EIS – Environmental Impact Assessment Air Traffic Environmental Program Federal Aviation 2 April 26, 2018 Administration
AIR TRAFFIC ENVIRONMENTAL PROGRAM Three Levels of NEPA Review • Categorical Exclusion (CATEX) – established list of actions that do not, individually or cumulatively, have a significant impact Environmental Assessment (EA) – analysis of proposed action and • reasonable range of alternatives that could result in preparation of an Environmental Impact Statement or Find of No Significant Impact • Environmental Impact Statement (EIS) – detailed analysis of environmental consequences and alternatives, cumulative impacts, and mitigation actions Air Traffic Environmental Program Federal Aviation 3 April 26, 2018 Administration
Categorical Exclusion (CATEX) • Action that does not have a significant impact on the quality of the human environment • FAA must review for extraordinary circumstances – Adverse effect such as cultural resources, air quality, etc. • FAA Order 1050.1 - list of FAA CATEXs – Establishes a list of common FAA actions that are CATEX’d – Example - Establishment of Global Positioning System (GPS), Flight Management System (FMS), Area Navigation/Required Navigation Performance (RNAV/RNP), or essentially similar systems that use overlay of existing flight tracks.

Environmental Assessment (EA) • Addresses environmental effects that are not anticipated to cause significant impact • Analysis that could result in preparation of an Environmental Impact Statement or Finding of No Significant Impact • When to prepare – – Proposed action has no CATEX – Normally CATEX but involves extraordinary circumstance – Action normally requires an EA – Action that is not known to require an EIS and is not CATEX Air Traffic Environmental Program Federal Aviation 5 April 26, 2018 Administration
Environmental Impact Statement (EIS) • Detailed analysis of environmental consequences of proposed action and alternatives, cumulative impacts and mitigation actions • When to prepare? – Based on an EA, a determination that the action would cause a significant environmental impact and mitigation would not reduce effects – FAA anticipates significant impacts, so prepare an EIS without first developing an EA Air Traffic Environmental Program Federal Aviation 6 April 26, 2018 Administration
Airspace Actions Typical Types of Actions – Jet Route Modification – Procedure Changes (RNP/RNAV, OPD, etc.) • Area Navigation Procedures (RNAV) • Required Navigation Performance (RNP) • Glide-path modifications • Altitude or lateral changes – Airspace Redesign- single site or regional Air Traffic Environmental Program Federal Aviation 7 April 26, 2018 Administration
